I thought of making my own mp3 player for my car from old pc bits. I did a quick search on google and found THIS great site dedicated to DIY car mp3 players. I think I'll try it out. I have a spare 4gig hdd somewhere and some old cpu's (pentium2 450mhz and some cyrix chips). I only need 2 get my paws on an old mobo and a small lcd screen :-/
